THOMAS STARR, or

NEW LISBON, OHIO.

Letters Patent No. 84,590, dated December l, 1868.

ANIMAL-POWER.

-p` The Schedule referred to in these Iietters Patentan making part of the same.

l To all whom it may concern.:

Be it known that l, THOMAS Sanne, ot' New Lisbon, in the county ot' Columbiana, and St-ate of Ohio, have invented certain new and useful lmprovenients in Tread-Powers; and' l do hereby declare that the following is a full, clear, and exact description thereof, reference heilig had to the actannpanying drawings, making part of this specitication, and to the letters of reference marked thereon, like letters indicating like parts wherever they occur.

To enable others skilled in the art to construct and use my invention, Iwill proceed to describe it.

My invention consists in certain novel improvements in the construction oi' a trezul-powcr, to be used for operating churns, grindstones, and for similar doniestic purposes.

Figure l is aside elevation, and

Figures 2 and 3 are views of portions vot' endless apron or web, shown detached. y The object of my invention is to construct a cheap, simple, and etticient power, capable. of being adjusted to adapt it to be used by animals of various weights and sizes, the better to accommodate the. wants ofthe community at large.

ln constructing my improved apparatus, I make a rectangular frame, A, in the usual form, and within it, longitudinally, I mount another ti'ame, B, consisting of two bars, somewhat longer than the. main frame, and united by cross-bans, at suitable. intervals. This frame B is pivoted at its front end to the niain'ii'ame A, and its rear endv is supported 011 pins inserted in holes C, of which there is a. series, as shown in tig. 1 the rear end of B thus being leftt'ree to be raised or lowered, as desired, as hcreinaiter explained.

In the rear end'of this frame B is mounted a' roller, l), there. being a. corresponding roller, 1)', located at the front end of the main frame A, and around these two rollers is vstretched an endless apron or web, C, upon which the animal isrto stand when operating the machine, a-s is usual in this class of motors.

rIhe frame B, at its rear end, is provided with a series of notches, o, in any of which the ljournals of the rollcr.D may he placed, so as to adjust its position to the length of the web l, which is liable to be.- come stretched by use.

Another roller, 7i, is located about midway ot' the frame B, for supporting the central port-ion of the web C, and prevent it from sagging with the weight ofthe animal. y

The web ,G is composed of two strips, 1r, ot' leather or other tiemble material, arranged, one at each side, and having slats, l), ot' wood, fastened transversely thereon, with blocks, m., secured upon cach alternate slat, at each end; these blocks 'n1 extending lengthwise directly over the strips r, and having their ends hevelled, as shown iii tig-l, so that the rear-end of each block inl shall lap over upon the'cnd of tlnstub joining one, and each block of the series at the same time resting upon three of the slats b, as represented in figs. l and 2. i

By this method ot' constructing the web or apron C, I am enabled to use. narrow slats and long blocks, se-

cured lby a single screw or holt., at each end of the i slats, to the strips lr, thereby enabling it to bend and pass freely around the rollers D and D', and at the same time so lock the slats and blocks upon one another as to render the web very rigid and strong, when stretched out straight, when it is to support the'animal.

Upon the joinnal ofthe roller D is-mounted a balance-wheel, E, one arm of which has a slat, (a in it, in which is secured a stud or pin, on which is pivoted one end of a pitman, l, the upper end of which is piv- -oted to a. lever, L, which is fulcruined upon a bolt, fi,

at the rear end of the main fia-me A, as represented in iig. 1, the rear end of the level' L projecting out beyond the rear end of the main frame, as shown.

Near the ti'ont vend of theY frame A is secured an upright bar, l, to which is attached a rod, e, forming a guide, between which, and the bar I, the front end oi the lever L plays, and is steadied and kept in position. Y The machine is intended for use by farmers and families generally wherever a small Apower is wanted for domestic purposes, such as churning, turning grindstoncs, opera-ting a washing-machinc, and all similar purposes; and it maybe operated by a dog, sheep, cali', or any similar animal; and by having the web C so arranged that its rear end can be adjusted so as to render it more or less inclined, it can beoperated by a lighter or heavier animal, according to circumstances. y

By this means, also, its speed may be varied and controlled, the speed being increased by inclining the web more, and decreased by adjusting it more nearly level.

By means of the slat a, in the arm of the wheel E,

the pin t can be set nearer to or further from the ccnt-rc, and thereby the length of the stroke of the lever L may be varied as desired; and by means ofthe series of holes n, the lever may be raised or lowered, to adapt it to churns of diiferent heights and sizes.

By this method of constructing my improved apparat-us, I produce a -very simple, cheap, and durable motor, adapted to all the varying conditions, wants, and purposes of the public generally, for domestic use.

Having thus described my invention,

Vllhat I claim, is-

l. The web @consisting of the strips or belts fr, having the slats b, and bevelled blocks m. connected thereto, and arranged as described.

Adjusting the rear end ofthe ti'ame B vertically, by changing the position of its supporting-pin in the holes C, ot' the frame A, substantially as herein described, for thc purpose of giving any desired incline to the -web C, as sctftbrth. y

3. The adjustable rollcl' h, and notches o, of the frame B, when constructed and arranged substantially as described, to compensate for the stretching cf the web (l, as sct forth.
